KOTOR-VEHICLE FIRE-ENGINE.

Ipeellloation of Letten Patent.

Patented July 16, 1918.

To all whom it may concern:

Be it known that we, Pinamar Gl Howe.I and Amas RAY Lantaarn, citizens of the United States of America, and residents of Anden son, county of Madison, State of Indiana, have invented certain new and useful 1mprovements in Motor-Vehicle Fire-Engines, of which the following is a full and clear specification.

The object of this invention is to rovide a simple tixe-engine apparatus w ich is adapted to be attached to an automobilez pre 'erably the machine known as the Fordf whereby the usual power plant on the vehic-1e may he used not only to drive the vehicle to the place of use, b t also to drive the pumping plant carried y the vehicle when it arrives at the tire, the pumping apparatus being preferably arranged to deliver either u plain stream of water or a chemical stream, as more fully hereinafter set forth.

Figure 1 is u plan view of a Ford chassis provided with my improved mechanism;

Fig. l is u side elevation of the same partly in sections Fig; 3 is a rear elevation partly broken away; and

Figs. 4 and 5 are detail views hereinafter described.

Referring to the drawing by reference cl'iuru'cters, a designates the usuul transmission of the vehicle, by the usual pro )eller slialti` for driving the vehicle througii the rear lliixle, c a dentalor double `clutch slidably Iunountod on u squared part of shaft d and iidapted to be rotated therewith. 0n the d ls mounted u frly rotatable )iniou i ich meshes with a gear f mountetll on a sha t y Ywhose rear end carries a s )rocket It whgch runs u chain i for driving t e pump. A I)nox o", arranged at the rear end of the trginsmisson a, houses the clutch members arid the gears e and f and permits effective lubrication of Said parts. The shaft g is ournaled in bearings b in the walls of the ox, and the transmission-driven shaft d is jourualed at its forward end in the bearing c in the front wall of the box and et its rear end in an axial lissage formed in a clutch member d which iS journuled in a bearing e supported in an annular inwardly-extending fla e f carried by the wir wall ofthe box. he clutch member d" is made rotatable Dwith the vehcledriving vehicle dri vi shaft b by being fitted over the squared end g thereof, this squared end being connected t0 the usual universal joint h mounted upon the rear wall of the box. This arrangement of parts makes a very compact and simple mechanisn'i, and the rear wall of the box is utilized as a support for the universal joint. This arrangement of parte adapts our gearing to be readily applied to the well known Ford type of automobile.

By shiftin the clutch c rearwardly, the usual propel er Vshaft of the vehicle will lndriven in the usual way, the shaft g being idle by reason of the loose mounting of the pinion c on the driving shaft d ol the transmission. By throwing the clutch c forwardly into engagement` with the pinion e, said pinion is thereby locked to the driving shaft d und the propeller shaft L ol' the mechanism is released, and the pump mec anisrn will then be operated throu fh the medium of the gears e, f, shaft g ant chain It will be understood that the transmission gearing a is of the usual type. so that whether the clutch c be in enltragt-ment with the pinion e for driving the pump or be in engagement with the propelel s luft, the usual change in speed can he accomplished without manipulatingr the clutch c. It will be observed that the clutch is at all times in engagement with the propellet shaft of the vehicle except whe'n the vehicle is at rest and the pumping apparatus is being driven from the power plant ot' the vehicle. In other words, ity will be understood that the clutch c is not manipulated at all in the control of the vehicle.

The chain i drives the pump crank shaftl j which is adapted to operate three pump plungers Je whose pistons work in three pump cylinders Z. these pump cylinders hcmg provided with a oomlnon inlet n'ululfold m and n common outlet manifold fn, the inlet` chamber m heilig provided with an inlet pipe o adapted to be connected by hose to the sour of water supply.

4 The outlet chamber n is provided With an outlet pipe p, to the end g of which a hose muv be connected. the pi e beiner provided with a valve 1'. Back ofI.) the valve rises a branch pipe e whose upper end is connected to the air chamber t; and from the pipe s extends a by-pass pipe u to the top side of a chemical tank o. This pipe'u is provided with a globe valve u vertically to a `point near the bottom of the and extends downV l chemical tank and is there provided with a nozzle w pointing downwardly. A branch pipe :v extends upwardly 'from the by-pass pipe 'u and is provfded with a valve y, the extremity z of this latter pipe being adapted to receive the inlet end of a hose of small diameter.

In the bottom of the tank is arranged an outlet strainer a which communicatesY with lo an outlet pi e b provided with a manually operable ta ve e and having its exit connectedwith theinlet chamber m of the um n Itpwill be" understood that a line of suc- L5 tion hose is to be attached to the inlet pape o and extended to the source of supply. ater passes into the inlet chamber m, thence through the piston valves and into the chamber n, whence it may pass out through any one or more of the outlet pipes p, s, and d',

suitable lines of hose being, of course, connected to whichever ones are used and the others being closed in any suitable manner. The air chamber t insures an even flow of Water Whichever nozzle is in use. .To prevent the pump bursting against undue pressure, a suitable relief valve g is provided f in the pipe connecting 'this chamber with the i outlet pipe p.

In case there is not a sullicient supply of Water in the source available, the chemical apparatus is brought into play, it being understood that the tank o is at all times kept filled With Water and the usual chemical substance. When this chemical apparatus is brought into action, the inlet pipe o is closed by a suitable cap (shown at h' in Fig. 3) and then va ve c is opened and the pump is operated u er low speed, the usual low 40 speed of the "Ford transmission being right. When: the pump is thus revolved slowly, the mingled chemical materials and water from the tank 'u are caused to pass through the pump and up through the pipe line u and out through the small hose that is always kept 'connected to the outlet nozzle a, a suitable basket being provided for holdingl this hose in a coiled or folded condition. W

en this chemical hose is employed, it will .0 be understood that the other outlets are closed. The pump being much larger than is required to supply the small chemical stream, surplus Water from the pump, when valve u is open, passes back into the chemical tank through the nozzle w, thus constantly and thoroughly agitating the chemicals in the tank and eliminating the necessity of employing a mechanical stirrer for that purpose. Thus constantly keeping the 60 chemicals stirred in the tank insures maximum effectiveness in thc chemical stream.

It will be observed that a' special advantage in connecting u a chemical apparatus in the manner lset orth to a direct plain G6 water pumping apparatus lies in the fact that the chemical apparaus is in condition for instant use when the motor vehicle arrives at the fire. It of course requires some little time to connect the source of supply to the inlet pipe by means of the suction hose after arrival at the fire, and during this very vital interval the chemical apparatus may be brought into use. The importance ofthis will be understood when it is remembered that in many parts of the country prompt arrival of the lire apparatus means that fires can be put out by the chemi cal apparatus alone.

The letter j designates a large filling opening at the. top of the tank r. If no other water supply is available, the fireman can replenish the water in the tank by pouring pails of water through this opening2 of course replenishing thc chemicals from time to time, the chemicals being automatically agitated bywthe surplus water passing into the tank through the nozzle w. It `will therefore be observed that my apparatus may be continuously used as a chemical extinguisher alone where there is not a sui- 9o cient water supply available to use plain Water.

It will be observed that the preponderance of Weight of theappihatus is located on the left-hand side of the vehicle. In order to'95 equalize this rcponderance of weight so that thc car will at all times carry level, two auxiliary supporting springs c are employed at the rear of the vehicle. These springs are supported on the usual leatI spring Z and their upper ends are arranged to engage under a bar m carried by the vehicle frame. Suitable nuts n are employed for varying the tension of the springs. By increasing the tension on the spring atA the left-hand side of the vehicle, the preponderance of weight at that side'will be neutralized and the vehicle frame will be maintained in a level position. The lower supporting-member o of each spring is adapted to be adjusted along the leaf spring Z to enable the springs to be properly udjusted under the bar m before they are tensioned properly. A desirable way of anchoring the lower member o' to the spring 115 l is to pivot the same to a clip p which is in turn anchored to the spring by having its pivot bolt y pass through the curled-up end of the top leaf of the spring, as shown in Fig.4 5, The tensioning nut n is threaded onto bolt fr which is threaded down thrgn rh the bar m and passes through a hdlemiiit e center of the upper spring-receiving cap s', said nut n bearing down on top of this cap.

It will be observed that an advantage in so compactly constructing the gearing for driving the vehicle and pump that it may be inclosed in a comparatively small box arranged close up to the usual transmissioncasing a and mounting the universal joint of the vebiele-p-ropellitig-shaft upon the rear wall of the box is that we avoid increasing thel angle of the propellmi-shaft to any material extent, so that. when the meehanism is adjusted to drive the vehiele` we. obtain praetieall)Y the same etlirieuey as is obtained when the universal joint. is mounted on the rear end ol` the transuiission-easing.

It will be observed that the short shaft .r/ is driven from the main driven-shaft ot' the transmission. and. sinee both the punti and the vehirle are driven from this sha t` d. it will be seen that the variable-speed meehanism ot' the. usual transmission is utilized t'or variablv1 driving either the pump or the vehiele.
